Spring security

Authentication: It is a process or action of verifying the identity of a user or process i.e. who are you?

Authorization: It is a process of checking the authority of a user to perform actions in the application i.e. what are you allowed to do?

Spring security form based authentication example

As we discussed in our earlier examples that Spring Security will create a default login form automatically and we do not have to create any new jsp page. But we can create our custom login page with form.
